How to disable click sound in WebBrowser Control

Question

I use Javascript to click a link in the webbrowser control. But I don\'t want to hear IE\'s \"click\" sound.

Is there any way to do this?

P.S.

Answer 1

I have wrapped this functionality into a ready-to-use class. I used part of the information from the selected answer and the MSDN reference.

Hope this is useful to someone.

Usage

URLSecurityZoneAPI.InternetSetFeatureEnabled(URLSecurityZoneAPI.InternetFeaturelist.DISABLE_NAVIGATION_SOUNDS, URLSecurityZoneAPI.SetFeatureOn.PROCESS, false);
